How to use?

imgStatus is triggered by events. The function defined on watch method is called whenever there is a trigger.

imgStatus.watch('.image', function(imgs){
    console.log(imgs.loaded); // Number of Images Loaded (Type: integer)
    console.log(imgs.failed); // Number of Images Failed (Type: integer)
    console.log(imgs.isDone()); // If already load OR fail every image (Type: boolean)
});

See the source code which was used in the above example

var imagesLoaded = document.querySelector('.images-loaded'),
    imagesFailed = document.querySelector('.images-failed'),
    imagesStatus = document.querySelector('.images-status');

imgStatus.watch('.image', function(imgs) {
    imagesLoaded.innerHTML = imgs.loaded;
    imagesFailed.innerHTML = imgs.failed;
    if (imgs.isDone())
        imagesStatus.innerHTML = 'Completed!';
});
